Lots. Full sun is best, that means full sun across and including the noon hour. A little afternoon shade won't hurt, but for the most part, keep those rays beaming!
How much water should you give them? I have one in a pot that made ot through the winter and came back in the same pot. I transplanted it into a bigger one and I am wondering if I can take it in for the winter as things just do not seem to come back in the spring as we have really crappy soil . Can I take it in this fall and how much water should it get now? It is outside in the full sun and seems to be doing well. Thanks.
